Preface

This booklet is intended to be a light introduction to some basic ideas in

controls. The objectives are to

Promote student interest in control engineering and systems science

Educate beginners and non-specialists

Entertain specialists and geeks

Typically, ECE students who have taken a Junior level (3rd year) Signals &

Systems course, and EE/ME/AE/ChE students taking a Senior level Controls

course, should find it easily understandable. I hope to do additional parts

(state-space methods, optimal control, nonlinear systems ….etc) in the future.

This material was originally prepared as a live presentation, therefore some

narrative explanations are missing. I have been too lazy to add them, and I hope

the reader can interpolate as necessary.

Finally, this is only a light introduction; if you are seriously interested in

controls, please take a course or get a real textbook- there are many good ones.
